experimental[patch]: Fix import errors and docs of experimental prompt injection identifier (#21586)

Browse Source 
**Description**

I noticed that code in experimental was not functional due to small
errors, and users were complaining at
https://stackoverflow.com/questions/78272521/hugging-face-prompt-injection-identifier
and https://github.com/langchain-ai/langchain/discussions/19995.

I know folks are busy with `v2.0` now, but I believe this is worthy fix
because it is isolated, minor, backwards compatible, and fixes an error
with current v0.1 code

**Issue**
https://github.com/langchain-ai/langchain/discussions/19995

**Dependencies**
None
